On Christmas we celebrate the birth of Jesus the true Son of the one, true God. God, the Father, acknowledged Jesus as His “beloved Son, with whom I am well pleased” (Matthew 3:17) and Jesus spoke often of his father, “every one who acknowledges me before men, I also will acknowledge before my Father who is in heaven; but whoever denies me before men, I also will deny before my Father who is in heaven” (Matthew 10:32-33).
However, heresies persist regarding the relationship of Jesus and God. Some heresies, such as the heresy of Photinus, claimed that Jesus was a good man, leading a good life, thereby merited being called a son of God through adoption. We know this to be false. Jesus is the “only son from the Father” (John 1:14) (note John sates that Jesus is the only son “from” and not “of” the Father). Other heresies (of Photinus, Sabellius, and Arius) contended that Jesus began to exist in time and that he came into exist separate from and after the Father. This is contrary to Jesus proclamation that, “I and the Father are one” (John 10:30).
